Background technology
WLAN channel list is the wireless channel that IEEE 802.11 (or being called WiFi) wireless network of law defined should use.802.11 working groups have divided 4 independently frequency ranges: 2.4GHz, 3.6GHz, 4.9GHz and 5.8GHz, and each frequency range is divided into again some channels.Each country oneself has formulated policy and has drawn up how to use these frequency ranges.
A lot of country has law to regulate the use of these channels, such as, maximal power level etc. within the scope of certain frequency.Virtual network operator should seek advice from local authorities, because these regulations may be out-of-date, overwhelming majority of countries all allows not need licensing in the world, uses the 1st channel to the 13rd channel.
Based on above feature, the transmitting wifi frequency of the network equipments such as most routers is all in 1-13 range of channels.Such as TP-Link 703N initial channel is 6 channels.The channel frequency that the most router of further investigation dispatches from the factory is 1,6,11 these 3 channels, reason is as follows: China supports 1-13 channel, and 1-13 channel is supported in Europe, and the U.S. supports 1-11 channel, Japan supports 1-14 channel, and as a whole, subset is 1-11 channel.Therefore, the automatic channel of equipment is set to these three channels of 1-6-11, is safer way.The probability of channel disturbance is minimum, even like this, along with the development of time, the increasing of wifi hotspot quantity in unit space, also can cause signal disturbing between the different wifi hotspot of same channel.Below illustratively channel interference problem:
Realize the frequency difference (as shown in Figure 1) that agreement needs 16.25MHz to 22MHz, otherwise adjacent channel overlap will produce interference each other.The clearly reasonable solution of suggestion of standard leaves 3 spacing to 4 channels to avoid interference.Actual frequency difference definite when using, depends on the selection of channel and the electromagnetic environment residing for equipment and data rate.
When the 802.11b reflectors of 2 or more are at identical spatial operation, its signal must be attenuated to be less than-50dBr simultaneously/or frequency have the spacing of 22MHz at least with anti-tampering.And in fact, when DSSS algorithm transmits data, using 20MHz bandwidth, the gap of remaining 2MHz is used as guard band, allows the electromagnetic wave attenuation of the frequency edges used avoid interference adjacent channel.
Attention: the frequency range indicating 40MHz in upper figure, 20MHz band spreading part can be identified as in the administration interface of many WiFi equipment, use channel number+expansion display: Channel 3=Channel 1+Upper or Channel5+Lower and Channel 11=Channel9+Upper or Channel 13+Lower.
In brief: the equipment in same channel is more, disturb larger, in close two channels, the quantity of equipment is more, affects more secondary than the impact of same channel, by that analogy.
